Deep Dive
1. Major SDK Overhaul & New Modules (September 2025)
Overview: This significant update to the TAC SDK (v0.7.0) makes it easier for developers to build complex applications. It introduces new tools for handling different types of digital assets and improves the reliability of sending transactions across blockchains.
The release added a dedicated Assets Module for working with fungible tokens, NFTs, and TON assets. It also introduced internal transaction simulation, which helps estimate costs and success before sending, and added support for sending transactions in batches, which can save time and fees. The SDK's core architecture was refactored for better performance and stability.
What this means: This is bullish for $TAC because it directly empowers developers. By providing more robust and user-friendly tools, TAC lowers the barrier to building dApps on its network, which could lead to more innovation and user adoption. Faster, more reliable transactions improve the overall experience for everyone.

2. Cross-Chain Transaction Enhancements (June 2025)
Overview: Updates in versions v0.6.3 and v0.6.4 streamlined how applications move assets between the TON and TAC blockchains. The key addition was the ability to send multiple cross-chain transactions at once.
Developers gained a new sendCrossChainTransactions method and batch sending support, making it more efficient to handle complex operations that involve several steps. The SDK also switched its default connection to use TAC-specific endpoints for better reliability.
What this means: This is bullish for $TAC as it enhances the core utility of the protocol: seamless bridging. Smoother and more efficient cross-chain transactions reduce friction for users accessing DeFi apps on Telegram, encouraging more frequent use and increasing network activity.

3. Fee Calculation & Sequencer Upgrades (May 2025)
Overview: The v0.6.1 and v0.6.2 updates focused on the economic and infrastructural backbone of cross-chain transactions, specifically how fees are calculated and processed.
The SDK integrated direct fee support for cross-chain transactions, adding methods like getTransactionSimulationInfo. It also upgraded to a "v3 sequencer" and introduced a lite sequencer client, which are systems that help process and order transactions more efficiently and accurately.
What this means: This is neutral-to-bullish for $TAC. While not a user-facing feature, reliable fee calculation and robust sequencing infrastructure are critical for network stability and security. This groundwork is essential for supporting high volumes of transactions as the ecosystem grows.
